SAFETY-EXPLOSIVE No. ss2,s1o.

Application filed June ilk 3.908.

To all whom it may concern:

Be it known that i, Bnnrnom; Grisriw RESCHKE, {I citizen of the German Empire, and resident of Hamburg, Germany, have invented anew and improved Safety-Explosive, of which the following a specification.

This invention relates to safety explosives more particularly for use in mines where it is most important to consider tire effects of the explosion gases, and its object is to provide ssiety explosives that shall generate explosion gases of a harmless nature and more 85 5% sinrnon ium iii 1; 1.0% iii-ohenzol 94.0% sninionimn nit 6.0% fennel 95.0% ammonium nitrate 1.0 %':(l1n1"tYOl Ei1Z0l .0% iennel These safety explosives have t power and are not readily ell'eeted by lengthy storing. This reat explosive power is due to the percentage oi ethereal oils contained in the seeds of fennel. However, I have ascertained that the xplosive energy and the resuiting expiosi 1 giv s can be greatly improved by the mixture oi iiue Wood pulp to the aforementioned explosives, thus 2- r 87.9% ammonium nitrete i 7ii%fenn el ("3.0% Wood pulp 861% elmmonium nitrate dinitrobenzol 6.6% fennel 5.7 W001i. pulp Specification of Letters Patent.

Serial No. 322,4;47.

94.3% ammonium nitrate 3.0% 'lennel 2.7% Wood pulp.

95.2% ammonium nitrate 1.0% dinitrobenzol fennel i .s% wood pulp p The addition of wood pulp is' of great edventage in the rnsnufeetureof these explosives, it absorbs the OllS oontained'in the lennelseeds, so that any stroking of the mixture to the reducing mill or mixing apparatus is prevented.

in order to render the same practieall safe fIOlll'fii'C-(lLIHP explosions lowing constituents and proportions viz:

ammonium nitrate fennel copper-oxalate snunoniu in nitrate iennel wood pulp dinitrobenzol r-o3uzlste onsls, e of copper nitrate of ammonia 5g, nitrate of pot-ash fennel.

"wood-pulp diuitrobenzol oxalate of copper What I claim is:

1. An ammonium nitrate explosive eon sisting' of ammonium nitrate and fennel seed in about the proportions stated. I

2. An ammonium .n'trote explosive sisting of ammonium nitrate, fennel seed and wood pulp, in about the proportions-stated.
